Description

[Detailed description of the invention] This invention relates to a support device for hanging rod members, and is used to attach ceiling plates and electrical equipment to a floor plate called F-deck, which is used when constructing concrete floor plates in concrete building construction work.・A suspension rod that is used to suspend suspension members such as suspension bolts that suspend and support various components for air conditioning and disaster prevention, and can be mounted and supported from below at any position after the floor plate is constructed. The present invention relates to a member support device.

Conventionally, concrete floor plates for concrete building construction are constructed using floor plates called F-decks, which are made by bending rolled steel plates of a predetermined thickness and arranging triangular reinforcing sections. In some cases, in order to suspend hanging rod members such as ceiling panels and hanging bolts that suspend and support various parts for electrical equipment, air conditioning, and disaster prevention, insert tools must be inserted from above after the floor plate is tensioned. The floor plate is temporarily fixed, concrete material is poured, and after construction, it is connected to the insert tool from below the floor plate by a predetermined means. However, according to this method, it is necessary to drill a mounting hole in the floor plate for fixing the insert, which may weaken the floor plate.
Not only does it have to be firmly fixed to withstand the shock and vibration of the concrete being poured, but it is also inefficient to work at a very crowded construction site, and it is difficult to suspend the suspension members. It was impossible to change the position at all.

Therefore, in view of the existing drawbacks as described above, the present inventors have made improvements from various viewpoints in order to eliminate these problems. This idea was completed by focusing on the use of sections.

This invention will be explained below with reference to the drawings.

That is, one embodiment of the present invention is a support device that is attached to a predetermined floor plate P by using a reinforcing portion S having a protruding approximately triangular cross section with a wide bottom and a narrow top. Reinforcement part S
A sliding support member 1 having a lip groove shape in cross section and having a lip 3 at the opening and having beveled edges 2 at both ends that are arranged perpendicularly to each other and abutting the outer surface of the reinforcing part S, and a sliding support member 1 that engages the inner surface of the lip 3. The sliding support member also includes a nut member 4 which is internally housed in the sliding support member 1 and to which a predetermined hanging rod member B is screwed, and a positioning protrusion 11 which is fitted between the lips 3. A positioning member 7, which has a cross-sectional groove shape and is fitted with a cover in an opening of 1, into which a predetermined hanging rod member B with a nut N is inserted, and a positioning member 7, which is screwed and removed so that the inside of the inner bottom wall of the sliding support member 1 can be freely advanced and retracted. , and a fixing screw member 12 whose tip is pressed against the lower surface of the floor plate P.

As shown in the figure, the sliding support member 1 is made of a well-known lip channel steel, and the floor plate P
Although the length is slightly shorter than the distance between the reinforcing parts S, when the openings of the reinforcing parts S are arranged perpendicularly between the reinforcing parts S with their openings facing downward, the lower end of the reinforcing parts S They are supported in an engaged state by their mutual smallest narrow portions. In addition, in order to be able to place the reinforcing part S at a predetermined position from below when installing it, it is preferable to insert it obliquely to the length direction of the reinforcing part S and then rotate it slightly so that it can be orthogonally arranged.

Further, the beveled edges 2 at both ends of the sliding support member 1 are formed at an inclination angle corresponding to the outer surfaces of the left and right side walls of the reinforcing portion S so as to be in close contact with the outer surfaces of the left and right side walls. The lip 3 is not limited to being formed by being inclined with respect to the side wall of the sliding support member 1 as shown in the figure.
It can be changed in various ways, such as being horizontal or having an L-shaped cross section.

Nut member 4 installed inside this sliding support member 1
is formed into a substantially rectangular planar shape with a width approximately corresponding to the internal width of the sliding support member 1 so as to prevent the hanging rod member B from idling when it is screwed in the interior state. Slightly inclined engagement pieces 6 are bent on both sides of the central portion where the female threaded hole 5 is formed so as to reliably engage with the inner surface of the inclined lip 3. The nut member 4 may be in the shape of a parallelogram that is inserted from between the lips 3 and engaged with the lips 3 by being rotated on a plane.

In the positioning member 7, the hanging rod member B screwed to the nut member 4 is penetrated, and the nut N is pressed against the lower surface of the positioning member 7, so that the lip 3 of the sliding support member 1, the nut member 4, and the nut N are inserted into the positioning member 7. At that time, the movement and wobbling of the nut member 4 itself is prevented, thereby preventing swinging of the hanging rod member B, and preventing the movement of the nut member 4 itself against the sliding support member 1. It is designed to be stable in a predetermined position. Therefore, in order to straddle the opening of the sliding support member 1 and be attached to it, a sliding member is attached to both ends in the left-right direction of the central piece 8, which has a through-hole 9 into which the hanging rod member B is inserted. The dynamic support member 1 has an inner width in the left-right direction that substantially corresponds to the outer width thereof, and has a cross-sectional groove shape formed by standing left and right pieces 10 facing each other, and has both end edges in the front-rear direction. A positioning protrusion 11 that is fitted between the lips 3 is provided upright. Positioning protrusion 1 as shown
1 is formed in the shape of Mt. Fuji with a beveled edge that abuts the outer surface of the inclined lip 3, but it is needless to say that the present invention is not limited to this.

Further, the fixing screw member 12 is screwed and protrudes outward from the bottom wall of the sliding support member 1, and its tip is pressed against the lower surface of the floor plate P.
The sliding support member 1 itself is pushed down and its beveled edge 2 is brought into pressure contact with the outer surface of the reinforcing portion S, and as a result, the sliding support member 1 itself is supported and fixed between the reinforcing portions S. It is. Therefore, it is desirable that the fixing screw member 12 is firmly screwed into the bottom wall of the sliding support member 1. In some cases, a reinforcing nut 13 is welded to the inner surface of the inner wall to strengthen the screwed portion and ensure the screw lead of the fixing screw member 12.

This invention is constructed as described above, and to explain its use, an example is a concrete floor plate C constructed through a predetermined construction procedure, and a floor plate P called an F deck. At a predetermined position between the reinforcing parts S, the sliding support member 1 is brought from below, placed orthogonally to the reinforcing parts S, moved in the length direction to position it (see Figures 3 and 4), and fixed. It is firmly fixed by screwing in the screw member 12. Furthermore, a hanging rod member B, such as a hanging bolt with a nut N, is inserted through the positioning member 7, and screwed onto the nut member 4 which is installed in the sliding support member 1 and is engaged with the lip 3, and the sliding member B is inserted into the positioning member 7. The dynamic support member 1 is moved and positioned in the length direction (see FIGS. 2 and 4). Next, the nut N is screwed in and pressed against the lower surface of the positioning member 7, thereby clamping the lip 3 and the positioning member 7 together with the nut member 4. As a result, the suspension member B is placed in the correct and required position. Hanged down. After that, various members L such as lighting equipment are attached and supported to this hanging rod member B.

Therefore, unlike in the past, after the construction of the concrete floor plate C is completed, the hanging rod member B can be directly suspended while confirming that it is in the required predetermined position, and the suspension member B can be suspended directly on the floor plate P. Since there is no need to drill holes in the ground, there is no need for wiring for electric drills, which eliminates the need for wiring for electric drills, and does not interfere with each other's work at complicated construction sites, greatly improving work efficiency. It also becomes possible to suspend the structure near the reinforcing portion S, which was previously impossible, without weakening the structure.

The beveled edges 2 at both ends of the sliding support member 1 abut against the outer surface of the reinforcing portion S, which has a substantially triangular cross section and is formed to protrude downward and has a wide bottom and a narrow top in the floor plate P. The sliding support member 1 is firmly and securely fitted between the adjacent reinforcing parts S, and cannot be pulled out even by the loads of the various members L applied via the hanging rod member B and the nut member 4. It is not done. Moreover, since the inside of the inner bottom wall of the sliding support member 1 is known and the tip of the fixing screw member 12, which is screwed so that it can move forward and backward, is pressed against the lower surface of the floor plate P, the tip of the fixing screw member 12 is pressed against the lower surface of the floor plate P. Since the beveled edges 2 are in close contact with each other, the sliding support member 1 does not move or wobble at all, and a more stable supporting force can be obtained.

Further, the positioning member 7 is arranged between the lips 3.
It has a positioning protrusion 11 that is fitted into the opening of the sliding support member 1, and has a cross-sectional groove shape that is fitted with a lid on the opening of the sliding support member 1, and is configured so that the hanging rod member B with a predetermined nut N is inserted therethrough. By clamping the lip 3 and the positioning member 7 with the nut member 4 and the nut N, the lip 3 and the positioning member 7 are securely positioned at a predetermined position with respect to the sliding support member 1, and are protected against external shocks and the like. To prevent rattling and to firmly maintain a hanging state of a hanging rod member B.

As explained above, according to this invention, after the floor plate is constructed, it can be mounted and supported from below at any desired position, and the hanging position of the hanging rod member can be freely selected and changed. It is possible to fit and fix the reinforcing parts to each other by pressing the fixing screw member against the floor board plate, and to suspend and fix the hanging rod member itself by clamping a lip etc. between the nut members. In addition to the fact that the floor plate does not require any special processing, it can be easily and quickly mounted and supported, and the structure is simple and can be provided at low cost, which is extremely beneficial in practice.
